IMPROVEMENT IN ABIRD-CAGES.

Specification forming part of Letters Patent No. 156,372, dated October27, 1874; application filed June 3, 1874.

To all whom it may concern:

Be it known that I, CHARLES L. OsBoRN,

of Brooklyn, in the county of Kings and State of New York, have inventeda new Improvement in Bird-Cage; and I do hereby declare the following,when taken in connection with the accompanying drawings and the lettersof reference marked thereon, to be a full, clear, and exact descriptionof the same7 and which said drawings constitute part of thisspecilication, and represent, in-

Figure 1, a side view; Fig. 2, a transverse section above the base; Fig.3, a detached view; Fig. 4, asectional view, illustrating thearrangement of the spring to close the feedbox 5 Fig. 5, a vertical,central section of the pan and base; and in Fig. 6 an under-side Viewof the central portion of the base.

This' invention relates to an ilnprovement in the construction ofbird-cages, such as are made from Wire with metal pans; and it consists,rst, in dividing the bottom hoop at one point, so that `it may becontracted to disengage from the hooks on the base or expand to engagethe hooks, as the case may be 5 second, in pivoting the pan to the base,so that the cage may be turned without turning the base.

The vertical wires of the cage may be of any desirable style. They arebrought down to a bottom hoop, A, as seen in Fig. 3, the said hoop cutas at a, and connecting the two ends is a bow-spring, B, the tendency ofwhich is to force the two ends asunder-that is to say, to expandthe'hook. Thisspring, however, is not essential, as the expandingelasticity may be entirely within the hook. On the pan, at severalpoints, a hook, d, is arranged, within which the hook, when it iscontracted, will pass, and when allowed to expand the hoop will passbeneath the hooks d, as seen in Fig. 2; then, when required to removethe cage from the pan, it is only necessary to draw the two ends of thehoop together to contract the circumference su'icient to pass from thehooks d. On one of the hoops B to which the feedboxes are pivoted, aspring, C, is arranged which bears against a flat surface on the pivot Yf of the feed-box when in a closed position. The opposite side of thepivot f is also flat. Hence, when turned to either the closed or openposition, the spring C will bear against these flat surfaces, andthereby hold the feedbox in either an open or closed position, as thecase may be, and the tendency of the spring is to throw the feed-box toeither of these positions when turned by hand to approach thesepositions. D is the pan, and E the base, in outline of any of the usualforms. Instead of being permanently or rigidly attached together the panis formed with a central depression, F, setting into a correspondingperforation in the base, which forlns a center upon which the pan mayturn. A stud, n, is attached to the center of the pan, and over this acollar, fm, is placed, with elastic arms r extending out to bear uponthe under side of the base. The stud is formed with an annular groove,t, and into this groove a slotted collar, s, is passed, bearing upagainst the collar m. This secures the base and pan together. Theelastic arms r yield or produce sufficient friction to retain the partsrmly together and yet allow the pan to be turned on the base withoutturning the base.

Other frictional devices equivalent to this described may be used andproduce the same result.

I claim as my invention- 1. The divided bottom hoop A of a birdcage,combined with the hooks d on the pan, substantially as described.

2.` The pan D of a bird cage, constructed with the central depression F,combined with a base, E, constructed with a corresponding perforation,and the collar m provided with elastic arms r, and locking device s,substantially as and for the purpose described.
